Gods of Strife, the fourth book in the Adept Series.
I got the first beta back yesterday. And I have to say, it was a good experience. The woman pointed out a few typos and misspellings. But she also had constructive criticism of some poor sentence construction and confusing things.
I didn't take all her advice. If the other two betas say similar things, I'll look into it. But some stuff I thought was a little like "if you'd read it more carefully, you'd understand what I'm trying to say here." And she said she was still worried a character was safe after my main character had practically said, "Oh, yes, he's safe now (and in bed with a woman)." If the other two betas have similar concerns, I'll look it over.
So over all, I'm finding beta reads to be useful.
